AB  - The aim of this work was to synthesize semiconducting oxide nanoparticles using a simple method with low production cost to be applied in natural sunlight for photocatalytic degradation of pollutants in waste water. Iron titanate (Fe2TiO5) nanoparticles with an orthorhombic structure were successfully synthesized using a modified sol-gel method and calcination at 750 degrees C. The as-prepared Fe2TiO5 nanoparticles exhibited a moderate specific surface area. The mesoporous Fe2TiO5 nanoparticles possessed strong absorption in the visible-light region and the band gap was estimated to be around 2.16 eV. The photocatalytic activity was evaluated by the degradation of methylene blue under natural sunlight. The effect of parameters such as the amount of catalyst, initial concentration of the dye and pH of the dye solution on the removal efficiency of methylene blue was investigated. Fe2TiO5 showed high degradation efficiency in a strong alkaline medium that can be the result of the facilitated formation of OH radicals due to an increased concentration of hydroxyl ions.

AB  - Electrochemical properties of oxide coatings formed by plasma electrolytic oxidation (PEO) on aluminum in sodium tungstate (Na2WO4 center dot 2H(2)O) with respect to process time were investigated using electrochemical impedance spectroscopy (EIS). Presence of tungsten was beneficial for the corrosion stability of obtained oxide coatings. However, neither the amount of tungsten in the oxide coating nor the coatings thickness were identified as important factors in corrosion stability of PEO coatings, i.e., morphology and porosity solely govern the corrosion stability of PEO coatings. The evolution of EIS spectra with immersion time for coatings anodized for 5 min and 7.5 min point to more efficient corrosion protection of aluminum substrate, compared to other tested samples.
